Application filed December 9, 1913. Serial No. 805,516.

To all whom t may concern.'

Be it known that I, WILLIAM M. RAP?, a citizen of the United States, residing at TWestmont, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Linotype- Machines, of which the following is a specilication.

My invention relates' to improvements in linotype machines; the object of the invention is to provide an improved construction of assembler slide, carrying one scale of a vernier gage registering with an adjustable fixed scale, whereby accurate measurements of the assembled line are always apparent from a glance at the registering scales.

A further object is to provide an improved construction of brake for the assembler slide.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in front elevation illustrating the assembling mechanism of an ordinary linotype machine with my improvements in operative position. Fig. 2 is a top plan view of my improvements detached. Fig. 3 is a view in section on the line 3 3 of Fig. 1. Fig. /1 is a view in section on the line 4-4 of Fig. 1. Fig. 5 is a view in section on the line 5 5 of Fig. 1. Fig. 6 is a view in section on the line 6-6 of Fig. 1. Fig. 7 is a view in section on the line 7-7 of Fig. 1. Fig. 8 is a perspective view of my improved brake shoe, and Fig. 9 is a view in section on the line 9-9 of Fig. 1.

1 represents a portion of the frame of an ordinary linotype machine, 2 the elevator, and 3 the star wheel which are common to machines of this type. While 1 have illustrated my invention in connection with such a machine, l would have it understood that my improvements are equally well adapted for use in connection with an intertype or slug casting or typesetting machine, and hence I do not limit myself to the particular use.

4t represents my improved assembler slide which comprises a channel bar movable through guides 5 and 6, said guides integral with a plate 7, and said plate adapted to be secured to the machine. One end of this slide 4L is connected by the ordinary link 8 with the ordinary spring 9 for returning the slide to normal osition with its linger 10 against the star wlieel 3. It will be noted that the finger 10 is rigidly secured to the slide L by screws 11, so that there can be no movement whatever of the finger relative to the slide.

An angular collar 12 having spacing blocks 12a therein, is adjustably secured to the slide l by means of a set screw 13, and this collar 12 engages the rear guide 6 to limit the movement of the assembler slide and regulate the length of the line of mat- -rices set up. The set screw 13 permits the line to be adjusted at will by moving the collar to any position on the slide.

`On the side of the collar 12, a perforated lug 12b is provided to receive a wire 12d held by a screw 12C. The wire may be inserted to blank off the scale where the operator wishes to line up, so that the length of line is always apparent.

A scale plate 14 is fixed to the assembler slide 4 and registers with a scale plate 15 secured to an angle bar 16. The lower member of the angle bar 16 is provided with a longitudinal slot 17 through which a screw 18 projects, said screw engaging in a threaded opening in an integral lug 19 on plate 7 and by this arrangement of parts, the scale 15 may be adjusted longitudinally. The scales 14 and 15 constitute a vernier gage, the former indicating in points, and the latter in picas, and by their combination indicating at all times the precise length of the line of matrices set up. By this arrangement of parts, the linger 10 may be rigidly ixed to the assembler slide 4: as above described, and yet allow of an accurate adjustment of parts to insure a perfect measurement even after the parts become worn, be'- cause in order to secure an accurate arrangement of the scale, it is simply necessary to move the slide to bring the linger 10 against the star wheel, and then adjust the scale 15 as above described to bring the scales to Zero.

It will be noted by reference to Fig. 1

that the spaces of the lower ixed scalel 15 are appreciably smaller than the spaces of the movable scale on the slide. To be more accurate, the scale 15 is divided into twelve equal parts, and the divisions of the scale 14 are each one-twelfth longer than the divisions of the scale 15.

The lower guide lug 6 is provided with an an ordinary slug 20b such as commonly made in linotype machines. This slug 20b will be positioned as shown in Fig. 1 when it isv when the line of matrices is elevated, as is customary in machines of this character, while the other end of said lever is movable between lugs 25 and 26 projecting inwardly from an arm 27 which latter is also fulcrumed between its ends on the reduced inner end 22 of turn button 23.

'I'he end of lever 21 is appreciably narrower than the space between lugs 25 and 26 to allow of a pre-determined movement of the lever, and this movement is regulated by a screw 28 screwed through luO' 26 and locked against accidental movement by a jam nut 29. One end of the arm 27 is formed on its inner face with an angular recess 30 to receive a tongue 31 integral with a plate 32 on which a strip 33, preferably of raw hide, is secured by screws 34. This plate 32, tongue 31, and strip of raw hide 33 constitute what I shall term a brake shoe,7 because the strip 33 is positioned within the channel bar assembler slide 4, and exerts frictional contacttherewith when the lever is in the position indicated.

A spring 35 is coiled at one end around the turn button 23 and projected through an opening 36 in the head of said turn button, while the opposite end of the spring exerts upward pressure on a lug 37 integral with arm 27 A screw 38 extends through the central bore of the turn button 23, and is screwed into plate 7 the head of said screw 38 being countersunk in the turn button. By releasing this screw 38, the turn button may be revolved to adjust the tension of the spring, and when the proper adjustment is had, the screw is screwed home to clamp the turn button against movement. The tension of the spring tends to move the arm 27 and the lever 21 in a direction to position the integral forwardly projecting tongue 20 havl ing a set screw 2Oa therein adapted to clamp strip 33 at a slight angle to the assembler slide 4. In other words, the tendency of the spring is to move the strip 33 out of parallelism with the slide 4, so that a strong frictional gripping action is had against the parallel members of t-he channel bar constituting the slide, holding the slide against any tendency of the spring 9 to return the same. Furthermore this construction of brake allows the slide to be manually operated at any time to move the slide in either direction and allow a wide range of manipulation with reference to the matrices and to the other parts of the apparatus without releasing the brake.

The particular connection between the end of lever 21 and the arm 27 allows a predetermined amount of independent movement 'of the lever before the brake is operated, this movement being regulated by the screw 28. Such an arrangement prevents any possibility Vof the brake being released by vibration of the parts, and also permits of a nice adjustment between the lever and the elevator to properly time the release of the assembler slide when the matrices are moved by the elevator.

In operation, as the matrices, indicated at 40, are pressed against the linger 10 by the star wheel 3, the assembler slide is moved against the action of spring 9. As the scale 14 is fixed to the slide 4, its indicating marks will register with the marks of the fixed scale 15, so that a glance at the scales will indicate at any and all times the exact length of the line of matrices set up, and also allow of a wide range of manipulation of the slide to take out matrices, or place spacers, or correct mistakes, without releasing the slide. In other words, not only does the scale accurately indicate to the operatorjust the measurement of the line, but permits the manipulation of the slide to correct mis-` l takes in the setting up of the matrices, and also enables the slide to be moved in either direction and held in any position of adjustment by reason of the particular brake. The slide can be easily released by operating the lever 21 when the spring 9 will return the slide to normal position. By adjusting the tension of the spring 25, ythe frictional engagement of the brake shoe is adjusted. This is important because in the course of time it becomes necessary to change the tension to secure the proper frictional engagement.

My improvements are so constructed and arranged that they may be readily attached to any ordinary machine in use, and will operate with equal efficiency upon old machines as well as new ones.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope oit the appended claims.
